[FIX] web: toggle a bool in a x2m with the view in edition

Before this commit, in a form view in edition, if you clicked a toggle
boolean in an X2many, the view was saved. A toggle boolean should not do
a save if the main view is in edit mode.

The solution is to save the record only if the view's root datapoint
is in edition.

How to reproduce:
- Go to a form view in edit mode with an X2many that contains a toggle
   boolean field.
- Click on the toggle boolean in the x2many

Result before:
    The view is saved.

Result after:
    The view is not saved and is still in edit mode.
